Description for 2025 GMC Sierra 1500 SLT Truck

The 2025 GMC Sierra 1500 SLT Crew Cab 4WD in Onyx Black offers a well-rounded blend of performance, technology, and capability with a strong emphasis on trailering and off-road readiness. Powered by the 5.3L EcoTec3 V8 engine paired with a 10-speed automatic transmission, this truck balances robust towing strength with smooth drivability. The SLT trim, equipped with the X31 Off-Road & Protection Package, enhances its terrain-handling capabilities through features like an off-road suspension, hill descent control, heavy-duty air filter, skid plates, and recovery hooks. The dual exhaust system and chrome accents also lend a more aggressive appearance.

Inside, the cabin is trimmed in Dark Walnut/Slate leather with heated and ventilated front bucket seats and heated second-row outboard seats, combining comfort with practical winter-weather functionality. The SLT Premium Plus Package brings added convenience with a power sliding rear window, wireless charging, and a premium Bose 7-speaker audio system. This model includes the SLT Convenience and Preferred Packages, integrating upgrades such as remote start, universal home remote, and a floor-mounted center console.

Connectivity is a strong point in the Sierra 1500 SLT. It includes multiple USB charge/data ports throughout the cabin, a Wi-Fi hotspot capability, wireless charging, and a built-in navigation system. The infotainment system is SiriusXM with 360L trial subscription capable and paired with HD Surround Vision for enhanced visibility when maneuvering.

Trailering technology is particularly robust. The truck comes equipped with the ProGrade Trailering System, Integrated Trailer Brake Controller, Hitch Guidance with Hitch View, and Trailer Side Blind Zone Alert. The In-Vehicle Trailering System App and Trailer Camera Provisions provide advanced tools for managing various towing configurations, and Rear Cross Traffic Braking supports safety while reversing with a trailer. The Auto-Locking Rear Differential and electronic precision shift add control and reliability during heavy-duty use.

Safety technology includes the Sierra Safety Plus Package, which bundles key driver assistance features such as Adaptive Cruise Control, Safety Alert Seat, Rear Pedestrian Detection, and Ultrasonic Front and Rear Park Assist. Rain-sensing wipers, LED cargo area lighting, and perimeter lighting round out exterior visibility features.

With 20-inch polished aluminum wheels and chrome wheel-to-wheel assist steps, the exterior balances form and function. Additional equipment such as a spray-on bedliner with GMC logo and all-weather floor liners enhance durability for work or recreation.
